A Nenana man was sentenced Friday to six months in prison as the result of a state and federal investigation into allegations he trafficked in the illegal sale of parts of migratory birds, other wildlife and marine mammals. Miles W. Martin, 61, pleaded guilty in March to four counts of a 28-count indictment charging him with violations of federal laws governing fish and wildlife. Specifically, he pleaded guilty to the illegal sale of migratory birds, violating the Lacey Act, smuggling goods from the United States, and conspiracy to violate the Lacey Act, which prohibits the illegal sale of wildlife.The plea agreement with federal prosecutors called for a prison term of six to 10 months. Along with his prison time, Martin’s sentence also includes a lifetime ban on the sale of wildlife parts, a requirement that he surrender to the government more than 900 pounds of wildlife parts — they include lion, bear, walrus ivory, parts of seal, polar bear parts, and elephant ivory — and a fine of $6,500. He also will have three years of supervised release after his prison term. Martin, who is an artist who has lived in Nenana for 38 years, was a regular vendor each year at the Tanana Valley State Fair. State and federal agents searched Martin’s home in April 2011 as part of a larger investigation involving other people who planned to sell hundreds of pounds of walrus tusks.
